Specification of Letters Patent.

Patented May 9. .1 SM 4:

. Application filed July 28, 1911. Serial No. 641,119.

To all whom it may concern:

Be it known that I, Aoens'ros VVEDDER-- BURN, a citizen of the UnitedStates, residthe county of Fairfax and- State of Virginia, have inventedcertain new and useful Improvements in.

Condensers for lVater-Jacketed Engines, of

which the following is a specification.

Thisinvention relates to improvements in cooling means for internalcombustion engines and relates especially to water-jacket ed engines.

The object of the invention is to provide means whereby the steamarising from the hot water jacketwill be condensed and re turn to thejacket, or to a Water tank and thence'to the jacket over and over again,thereby requiring a much smaller quantity of tank water and eliminatingthe danger of the Water supply becoming exhausted.

With the above. and other objects in view which will hereinafter be morefully eX- plained, I have invented the device shown in the various formsof the invention in which 1 Figure 1 is a vertical sectional View of awater-jacketed engine cylinder and condenser, Fig. 2 is a sectional viewtaken on line A-A thereon, Fig. 3 is an elevatignal sectional view of amodified form of the invention, Fig. 4- is a vertical sectional view ofanother form of the invention, Fig. 5

is a view similar to Fig. 1 of another modi- "fication of the invention,Fig. 6 is an end elevational view of Fig. 5 partly broken away, Fig. 7is a vertical sectional View of another modification of the device, andFig.

8 is a view similar to Fig. 7 of still another mounted above the tank orhopper 16, and

securely sealed theretoisa casing 14: being open at its opposing ends. Aseries-0f U- shaped' pipes 8 have their ends 9 fixed in the lower wallof said casing 14,, said pipes opening on the hopper 16whereby steam.

may arise into the pipes 8 where it is condensed. These pipes 8 are keptcool by means of a constant draft of air passing through the casing 14,the entlre end lit 01 said casing being open in order that the passageof air will not be, retarded in pass ing from the casing. The series ofpipes 8 are so spaced that the draft of air will. halve free access toall parts thereof by which means said pipes arekept sufficiently cool tocause condensation of any steamarising thereinto. The water produced bythis con- (lensing process will naturally flow back into the hopper 16and thence to the. water jacket 2, thus at all time providing asufficient water supply for cooling the engine cylinder.

A fan 11 of any suitable character may be provided adj acent the opening12 in the end 13 of said casing 14 in order to produce artificial draftfor cooling the pipes8. A safety valve 15 may" be connected with one ofthe pipes 8 or at any convenient point on the hopper 16 or condenser inorder to relieve heavy steam pressure.

Where a condenser is to be used in connection with an automobile oraeroplane engine, it will be so positioned on the vehicle that thenatural draft of air will be sufli cient to cool the condenserpipess. 1

In Fig. 3 I show a different form of condensing chamber which consistsofa closed cylinder 21 having tubes 24.- extendinghorizontallytherethrough, the ends of which are mounted in the walls 22 and 23 ofsaid cylinder :21. In this form of the invention the passage of airthrough the tubes 2% cools the interior of the cylinder 21where thesteam is condensed, the condensed water passing either through the tube20 into the hopper 13 or it may pass directly from the cylinder 21 intothe hopper as shown in the construction illustrated in Fig.. 5.

' In Fig. 4c-is another modification of the invention in which thecondenser" is in the form of a drum 25 which consists of a-.-ser1es offins :26 whereby cooling surface exposed to the air on the outside andto the steam on the inside is greatly increased 1. In combination With aWatenjacketed steam condensing chamber, said chamber and jacket being sorelatively positioned that re-condensed steam will return by gravity tosaid jacket, said chamber being supported by said jacket, said chamberconsisting of a plurality of pipes, and means whereby an air current may.be directed against said pipes, said last means consisting of a fan.

2. In combination-with a water-jacketed engine cylinder, an independentclosed steam condensing. chamber, said chamber and jacket being sorelatively positioned that re-condensed steam will return by gravitytosaid jacket, said chamber being sup ported by said jacket, said chamberconsisting of a plurality of pipes, and means whereby an air current maybe directed.

against said pipes, said last means consisting of a fan, and a hood forsaid pipes.

3. In combination'with a water-jacketed engine cylinder, an independentclosed steam condensing chamber, said chamber and jacket being sorelatively positioned that re-condensed steam will return by gravity tosaid jacket, said chamber being supported by said jacket, said chamberconsisting of aplurality of pipes, and means whereby an air current maybe directed against said pipes, said last means consisting of a fan, anda hood for said pipes, said hood being open at its opposing ends.

4. In combination with a water jacketed engine cylinder, an independentclosed steam condensing chamber, said .chamber' and jacket being sopositioned thatrecondensed steam will return byv gravity to said jacket,said chamber being supported by said jacket, said chamber consisting ofa plurality of pipes.

5. In combination with a water jacketed engine cylinder, an independentclosed steam condensing chamber, said chamber and jacket being sopositioned that recon densed steam will return by gravity to saidjacket, said chamber being supported by said jacket, said chamberconsisting of a plurality of pipes, and means'whereby an air current maybe directed against said pipes.

6. The combination of a Water jacketed engine, a closed condensingchamber mounted on the water jacket, said chamber having a plurality ofcondensing units. a

In testimon whereof I aflix my. signature in presence 0 two Witnesses.
